Answer:
D. x = +-3*sqrt(2)
Step-by-step explanation:
x^2 = 18
x = +-sqrt(18)
x = +-sqrt(9 * 2)
x = +-sqrt(3^2 * 2)
x = +-3*sqrt(2)
Answer: b
When you add the same number to both sides it maintains equality
I think option B is a good one.
Since the triangle is equilateral (you can tell by the tick on each side), all angles have the same measure as well.
The angles of a triangle sum up to 180 degress, so three equal angles must measure 60 degrees each.
So, in particular, we have
7x + 4 = 60 7x = 56 x = 8
